Conference Object Citation - WoS: 2Citation - Scopus: 2Performance and Complexity Analysis of Suboptimal Mimo Detectors(Institute of Electrical and Electronics Engineers Inc., 2005) Özbek, Berna; Le Ruyet, DidierIn this paper, we consider coded MIMO systems using suboptimal iterative receivers. We propose to use the list type breadth first detectors based on M and TM algorithms and the soft output linear MMSE detectors with a priori information. We compare these two families of suboptimal iterative receivers in terms of complexity and bit-error-rate performance.Conference Object Citation - WoS: 3Citation - Scopus: 6Approximate Stationary Density of the Nonlinear Dynamical Systems Excited With White Noise(Institute of Electrical and Electronics Engineers Inc., 2005) Günel, Serkan; Savacı, Ferit AcarIn this paper, obtaining approximate solution of Fokker-Planck-Kolmogorov (FPK) Equation using compactly supported functions has been discussed. With specific choice of such functions as piecewise multivariable polynomials which are supported on ellipsoidal regions, the parameters to be determined can be considerably decreased compared to Multi- Gaussian Closure scheme [1]. An example commonly considered in the literature has been analyzed and the proposed method has been compared with the Multi-Gaussian Closure scheme. The simulation results indicate that the new scheme is quite successful even if the driving noise is not white Gaussian, but has an exponential correlation function with small correlation time.
